Which integration approach best fits this requirement in Cloud Pak for Integration?

A team is new to IBM Cloud Pak for Integration and wants a single place to discover, try, and reuse integration assets (APIs, event streams, and integration flows) across multiple runtimes. Which capability best addresses this requirement?

An API provider wants to enforce a simple spike arrest policy to limit bursts of API traffic at the gateway. Where is this enforcement most appropriately configured?

A developer needs to send and receive messages with existing applications using industry-standard JMS semantics. Which Cloud Pak for Integration capability is the best fit?

A company wants to expose an internal API to external partners. They require consumer onboarding, application registration, and subscription/plan management without giving partners access to internal systems. Which approach best meets this goal?

An integration flow must transform inbound JSON into a canonical format and then invoke an API. The team wants to externalize endpoint URLs and credentials so they can promote the same flow across environments (dev/test/prod) without changing the flow logic. What is the recommended approach?

A solution requires event-driven integration where multiple consumers can independently read the same event stream and replay events for a period of time for troubleshooting. Which capability is most appropriate?

An administrator notices intermittent failures when calling APIs through the gateway. Backend logs show requests arriving, but clients receive occasional TLS handshake errors. Which is the most likely area to investigate first in the platform?

A regulated enterprise needs strict workload isolation between two business units using Cloud Pak for Integration on the same OpenShift cluster. They want separate administrative control and reduced blast radius while still using shared cluster infrastructure. Which design best supports this requirement?

An API must be protected so that only clients with valid OAuth tokens can access it. The organization wants centralized authorization and token validation at the gateway, not in each backend service. What should be implemented?

A mission-critical messaging workload requires guaranteed once-and-only-once processing semantics for a consuming application, even during pod restarts. Which combination is most appropriate to achieve this with IBM MQ-based integration?

An integration team wants to expose a backend REST service through API Connect and ensure that only approved clients can call it. Which built-in capability best addresses this requirement?

A developer is designing a synchronous integration that calls a downstream system which may respond slowly. What is a best-practice approach in App Connect Enterprise (ACE) to avoid thread starvation under load?

An operator needs to store TLS certificates used by integration endpoints in a secure, Kubernetes-native way on OpenShift. Which resource should be used?

A solution architect must explain what “capabilities” represent in IBM Cloud Pak for Integration. Which description is most accurate?

A team wants to make an API available to consumers with different plans (e.g., internal vs. partner) and apply different rate limits per plan, without duplicating the API definition. In API Connect, what is the best approach?

An integration uses IBM MQ and must ensure messages are processed exactly once by the consuming application even if the consumer crashes mid-processing. Which design best supports this requirement?

After deploying a new integration runtime, the pods start but the route is not accessible externally. Internal service connectivity works. Which OpenShift component is most directly responsible for exposing HTTP(S) access from outside the cluster via a Route?

A solution needs to integrate multiple SaaS applications and on-prem systems with minimal custom code, primarily using prebuilt connectors and mappings. Which Cloud Pak for Integration capability is best suited for this use case?

An organization wants to enforce a consistent API security baseline across many APIs (e.g., validate JWT, enforce TLS, and apply threat protection) while allowing teams to add API-specific logic. What is the most maintainable approach in API Connect/DataPower?

A team deploys an event-driven architecture using Event Streams. They require that events for the same customer are processed in order, but they also want high throughput across many customers. Which Kafka topic/producer design best meets this requirement?

A team needs to expose a set of microservices through a single entry point and enforce consistent policies (security, rate limits) across all APIs. Which Cloud Pak for Integration capability best fits this requirement?

An administrator needs to verify the health of Cloud Pak for Integration platform components and quickly identify which operand is failing. What is the most appropriate first place to look in OpenShift?

A solution architect wants to ensure messaging data is preserved across pod restarts and node failures for IBM MQ running on OpenShift. Which design choice is most critical?

A bank wants to separate responsibilities so that API providers can publish APIs, while a security team centrally controls runtime policy enforcement. Which API Connect model best supports this separation of duties?
